Step 2

Connect your iPhone/iPod Touch/iPad to iTunes 10.5 or later, hold down the Shift (Windows) or Alt/Option (Mac) key and hit the restore button on iTunes and then browse select the downloaded iOS 5.0.1 IPSW file (Unlockers MUST use Custom Firmware).

Step 3

Once the restore process is completed;
Run RedSn0w;
Select Jailbreak;
Then check “Install Cydia” and hit the next button.

Step 4

Now make sure your iPhone, iPad or iPod Touch is turned OFF and Plugged in to your computer. Hit Next.

Step 5

Now follow the on-screen instructions to enter your device in DFU mode.

Hold Down The Power (Corner) button for 3 Seconds

Without releasing the Power button, also hold down the Home (Bottom Center) button for 10 seconds

Without releasing the Home button, release the Power button BUT KEEP holding the Home button for 15 seconds

As soon as your iDevice enters DFU Mode, RedSn0w will start jailbreaking it, which should be completed within few minutes. That’s it!

Just updated from 4.2.1 to 5.0.1 and jailbroken but somethings not downloading keep getting size mismatch for items I had downloaded in the past. Anyone have any recommendations ? Any help much appreciated

You can. Download 5.0.1 from the links here on the site. DL redsn0w and go to the Extras button on the program. Use custom firmware option. Update phone in iTunes using NO_BB firmware created by resn0w. Jailbreak with redsn0w and install ultrasn0w. Reboot and enjoy.

I created a custom firmware as I need preserve the baseband to unlock but after installing the custom firmware and then trying to jailbreak redsn0w produces this error dialogue: ‘The IPSW for the following build is needed: iPhone2,1_5.0.1_9A404 The required IPSW is either not public or not available right now. PLease provide it manually using “Extras->SelectIPSW”. Note: If you provide this IPSW once, it will be cached so you don’t need to provide it again.’
Redsn0w does not proceed after this message pops up, any help with this will be much appreciated. I have a iPhone 3GS by the way.

I have gone over the steps continuously and still cannot get my iPhone 4 Verizon into DFU mode. I get through the first and second countdowns but when I just hold the home button on the third countdown it gets down to 9 secs and then it goes through two steps and then stops at waiting to reboot. My phone reboots back to normal. Nothing else. I am trying this on a pc, have tried all 3 versions of redsnow, disabled security …help!

if i create a 5.0.1 custom firmware for my iphone 3gs with baseband …and then restore it to the custom firmware ..and jailbreak using redsn0w …will it surely hacktivate my iphone ???
i rely on hacktivation …as i do not have an official SIM !

Tried to update my iPhone 4 and iPad 1 to 5.0.1 from 4.3.1. Ran the update/jailbreak (used redsnow) and it seems like the update went ok…

However, after it did the jailbreak when it goes to reboot the device, both my iPad and iPhone do the same thing. The apple logo appears, sits for about 1 min, then recycles and repeats. Can’t get either device to boot up and I have no idea why it’s doing that… anyone have an idea and/or suggestion? Thanks
